Abstract
Computer simulation is carried out to investigate the impact of Cross-Phase Modulation (XPM) on the Bit Error Rate performance of a single segment and multi-segment periodically amplified Wavelength Division Multiplexing (WDM) Intensity Modulation with Direct Detection (IM/DD) transmission system at a bit rate of 10Gb/s with Standard Single Mode Fiber (SSMF). A simple two channel WDM transmission system, one is effected channel under investigation known as probe channel and the other is the interfering channel known as pump channel are co-propagating inside the SSMF. The results show that XPM induced eye penalty increases with the increase of pump channel power and decreases with the increase of channel spacing between probe and pump channel. For 5dB penalty, the maximum allowable pump channel power is found to be 6dBm and 8dBm, for multi-segment and single segment WDM system respectively. For 3.5dB penalty, the minimum channel spacing is found to be 60GHz and 100GHz for multi-segment and single segment WDM system respectively. Multi-segment periodically amplified configuration can be used to reduce the XPM induced eye penalty for WDM system that requires a high probe power, low probe power and high channel spacing.
